+# Third-Party Tutorials: Consuming OpenXR Hand-Tracking Data
+
+## Introduction to Virtual Reality, OpenXR Hand-Tracking, and Gesture Detection in Unreal Engine
+
+In this tutorial, you'll learn how to get the OpenXR Hand-Tracking Data from the Unreal Engine API and how to consume it to draw virtual hand models using cubes (as hand joints). It will also dive into gesture recognition by implementing a simple pinch gesture recognition.
+
+In the first part, it will focus on UE `4.26` to `5.4` API. And, in the second part, you'll learn how to update the project to work with `5.5`.

+## Procedural Virtual Hand Mesh Animation Using OpenXR Hand-Tracking Data
+
+Building on the [Introduction to Virtual Reality, OpenXR Hand-Tracking, and Gesture Recognition in Unreal Engine tutorial](#introduction-to-virtual-reality-openxr-hand-tracking-and-gesture-detection-in-unreal-engine), this slightly more advanced tutorial will dive deeper into the following topics:
+
+- Transitioning seamlessly between motion controller and hand-tracking modes in Unreal Engine.
+- Adding custom debugging gizmos to improve development and testing workflows.
+- Visualizing debug virtual hands by incorporating the custom gizmos.
+- Animating virtual hand meshes with OpenXR hand-tracking data, moving beyond basic joint representation with cubes.
+- Re-using and adapting the gesture recognition code from the introductory tutorial to integrate with the new animated virtual hand meshes.
+This guide will help you take your VR projects to the next level with polished and practical implementations.

 The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
 and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
 
+## [2.4.0] - 2025-02-14
+
+This minor release brings various improvements and, notably, the first version to add support for VIVE standalone mode with ViveOpenXR compatibility.
+
+### Added
+
+- Added the ePub version of the SenseGlove Unreal Engine Handbook.
+- Added `FSGConnectJNI::Initialize()` and `FSGCoreJNI::Initialize()` return codes to Android logs for detailed debugging purposes through `adb logcat`.
+- Introduced compatibility with the `ViveOpenXR` plugin.
+- Added the `FSGPluginUtils` utility class for other plugins or modules availability detection such as `Meta XR` and `ViveOpenXR`.
+- Added various HTC HMDs auto-detection support on Android.
+- Added support for HTC VIVE Focus Vision HMD auto-detection.
+- Added support for HTC Vive Wrist Trackers support on Android using the official `ViveOpenXR` plugin's OpenXR positional tracking provider `OpenXRViveWristTracker`.
+- Added enum `ESGOpenXRPositionalTrackingProvider`.
+- Added the `OpenXRPositionalTrackingProvider` option to the plugin's wrist-tracker settings to either manually set the positional tracking provider or auto-detect it based on a combination of tracker hardware settings, targeted platform, available OpenXR plugins, or the auto-detected HMD hardware.
+
+### Fixed
+
+- Fix a critical issue where `HandStates->GetTransform(KeyPoint)` was incorrectly resolving to `(&HandStates[0])->GetTransform(KeyPoint)`, causing both hands to use the left hand's wrist transform under specific conditions. This occurred when the `bFallbackToHandTrackingIfNoGloveDetected` option was enabled, two gloves were present, and no hardware wrist-tracking device was active, resulting in both hands overlapping at the same transform.
+- `FSGArrayUtils` optimizations that affect the plugin performance as a whole.
+- Additional minor fixes and improvements that may not be listed here.
+
+### Changed
+
+- Now the motion sources for the wrist-tracking hardware or hand-tracking are queried and populated dynamically rather than relying on the hardcoded `EControllerHand` enum. This allows the SenseGlove Unreal Engine Plugin to integrate better into other plugins such as `ViveOpenXR`, which when enabled, provides many more options as the motion source for their various wrist-tracking hardware.
+- `FSGWristTrackingSettings::LeftHandMotionSource` and `FSGWristTrackingSettings::RightHandMotionSource` types have changed from `EControllerHand` to `FName`.
+- Bumped the SenseGlove libraries to `v2.105.3-97ea18cb`.
+- Bumped the SenseGlove Unreal Engine Marketplace Packager `v0.5.0-7df1183`.
+- Bumped the copyright years.
+- This is the last release to support Unreal Engine `5.2`. From `v2.5.x` onwards only UE `5.3` and newer will be supported.
+- The `ESGViveHMDDetectionPriority` enum items have changed and are no longer backward-compatible.
+
+### Deprecated
+
+- This is the last minor release to support Unreal Engine `5.2` and its support will be removed from the next minor or major releases.
+
+### Documentation
+
+- Reintroduced the Handbook in ePub format.
+- Revamped the [Enabling XR_EXT_hand_tracking OpenXR Extension on VR Headsets](../getting-started/enabling-xr-ext-hand-tracking-vr-headsets/) and [Deploying to Android (Standalone)](../misc/android-standalone-deployment/) documentation, and added the `ViveOpenXR`-compatibile instructions as well.
+- Significantly improved the [Setting Up the Wrist Tracking Hardware](../getting-started/setup-wrist-tracking-hardware/) section by providing more detailed documentation and example configuration per HMD and wrist tracking hardware.
+- Clarified [how to set up the VIVE Wrist Trackers in various configurations](../plugin-configuration/plugin-settings/tracking/wrist-tracking/).
+- Added [HTC VIVE specific optimization tips for running in standalone mode](../misc/optimize-higher-fps/#htc-vive-specific-optimizations-in-standalone-mode)
+- Fixed a few broken URLs caused by bad markdown formatting.
+- Applied various Handbook Makefile fixes.
+- Clarified the HTC VIVE standalone support status in the platform support matrix.
+- Bumped the [mdbook-alerts](https://github.com/lambdalisue/rs-mdbook-alerts) crate to `v0.7.x`.
+- Reintroduced [mdbook-epub](https://github.com/Michael-F-Bryan/mdbook-epub) at [`d1536bbbdc1ca00320522ad73a967e15057ef573`](https://github.com/Michael-F-Bryan/mdbook-epub/commit/d1536bbbdc1ca00320522ad73a967e15057ef573) from the [`master` branch](https://github.com/Michael-F-Bryan/mdbook-epub/tree/master) as the blocking issues in [#115](https://github.com/Michael-F-Bryan/mdbook-epub/issues/115) have been address in [`1ca2a860f6ed405c00914a3aadd8057d5050b29b`](https://github.com/Michael-F-Bryan/mdbook-epub/commit/1ca2a860f6ed405c00914a3aadd8057d5050b29b#diff-b21e2a96624fabac44d6c5ecc34bff0835565999be6a320fe75bd0401d5c8e87R148).
+- Added third-party tutorials to the following sections: [Enabling XR_EXT_hand_tracking on VR Headsets](../getting-started/enabling-xr-ext-hand-tracking-vr-headsets/third-party-tutorials/), [Deploying to Android (Standalone)](../misc/android-standalone-deployment/third-party-tutorials/), and [OpenXR](../advanced-topics/openxr/third-party-tutorials/).
+- Additional minor fixes and improvements that may not be listed here.
+- List the VRExpansionPlugin demo in the [Extra Resources](../appendix/extra-resources.html) section.

-Starting from version `v2.1.0`, the SenseGlove Unreal Engine Plugin requires the `XR_EXT_hand_tracking` OpenXR extension to function. If you are streaming from your PC to your VR headset, to enabling `XR_EXT_hand_tracking` support, might require additional settings depending on the vendor.
+Since version `v2.1.0`, the SenseGlove Unreal Engine Plugin requires the `XR_EXT_hand_tracking` OpenXR extension to function. Whether you are streaming your immersive 3D VR application from your PC to your VR headset, or deploying it to your VR headset in standalone mode, enabling `XR_EXT_hand_tracking` support, might require additional plugins or settings depending on the HMD's vendor or model.
 
-For Meta Quest headsets, enable the `Developer runtime features` under the `Settings > Beta` section:

-> [!CAUTION]
+## Standalone Mode
-> Streaming to Meta Quest headsets from SteamVR is no longer supported because
-> the migration to OpenXR has caused controller offsets for Meta Quest HMDs to
-> break on SteamVR. One possible reason is that
-> [SteamVR lists `XR_FB_hand_tracking` as an unsupported feature](https://steamcommunity.com/app/250820/discussions/8/3121550424355682585/).
-> Further investigation is needed to identify the exact underlying cause.

-As mentioned in the `v2.1.0` release changelog, enabling the Meta XR plugin—and potentially the VIVE OpenXR plugin—alongside the SenseGlove Unreal Engine Plugin in the same project will disrupt the OpenXR functionality provided by the SenseGlove Plugin, rendering it unusable.

-> `Although the SenseGlove OpenXR implementation is fully compatible with the IOpenXRHMD interface and the FOpenXRHMD XRTrackingSystem, it is not compatible with the FOculusXRHMD backend provided by the Meta XR plugin.

So, if these plugins are enabled in your project, the SenseGlove OpenXR will not function as intended, effectively breaking the plugin's functionality. It seems these plugins are necessary in order to make the fallback to the hand-tracking feature work on Android. While we may add support and compatibility with Meta XR and VIVE OpenXR plugins in the future, for the time being, if your project requires these plugins, we advise continuing with the v2.0.x release of the SenseGlove Unreal Engine plugin until this issue is addressed.`

+# Enabling XR_EXT_hand_tracking OpenXR Extension on VR Headsets in PCVR Mode
+
+Starting from version `v2.1.0`, the SenseGlove Unreal Engine Plugin requires the `XR_EXT_hand_tracking` OpenXR extension to function. If you are streaming your immersive 3D VR application from your PC to your VR headset, enabling `XR_EXT_hand_tracking` support, requires additional plugins and settings depending on the HMD's vendor or model.
+
+## Enabling OpenXR Plugin and Disabling OpenXRHandTracking Plugin
+
+Regardless of the type or vendor of the HMD you have in mind for development or deployment purposes, the `OpenXR` plugin is required as a prerequisite. Also, ensure the `OpenXRHandTracking` is disabled as it conflicts with the SenseGlove Unreal Engine Plugin since both implement the same `XR_EXT_hand_tracking` OpenXR extension.
+
+Though [enabling the SenseGlove Unreal Engine Plugin](../../plugin-verify-version-enable/) should enable the `OpenXR` plugin automatically, it is recommended to ensure this plugin is enabled, and most importantly `OpenXRHandTracking` is disabled, by navigating to `Edit > Plugins` in the Unreal Editor menus.

+
+## Meta Quest
+
+To set up `XR_EXT_hand_tracking` support on Meta Quest HMDs in PCVR mode, depending on your project requirements (e.g. whether you rely on the `Meta XR` plugin or not), additional setup steps are required.
+
+## Meta Quest Link App
+
+For Meta Quest headsets, enable the `Developer runtime features` under the `Settings > Beta` section inside the Meta Quest Link app:
+

+> Further investigation is needed to identify the exact underlying cause.
+
+### Meta XR Plugin
+
+> [!CAUTION]
+> Please note that enabling the `Meta XR` plugin alongside the SenseGlove plugin

+
+## HTC VIVE
+
+To set up `XR_EXT_hand_tracking` support on HTC VIVE HMDs in PCVR mode, additional plugins or configuration steps are required.
+
+### OpenXRViveTracker Plugin
+
+To enable VIVE Trackers support ensure the `OpenXRViveTracker` plugin is enabled by navigating to `Edit > Plugins` in the Unreal Editor menus. This plugin should be enabled, or wrist tracking won't function on VIVE devices at all.
+

+
+The `OpenXRViveTracker` plugin implements the `XR_HTCX_vive_tracker_interaction` OpenXR extension which is necessary to use VIVE Trackers or to [emulate the VIVE Wrist Trackers as VIVE Trackers on Windows](#vive-business-streaming-app).
+
+### VIVE Business Streaming App
+
+For VIVE headsets relying on the VIVE Business Streaming application, ensure the Hand Tracking settings under `Input` are enabled and `XR_HTCX_vive_tracker_interaction` is enabled for VIVE Wrist Trackers by enabling `Emulate VIVE Wrist Tracker as VIVE Tracker`:

+
+> [!NOTE]
+> Tracking and accessing `FXRMotionControllerData` output from SenseGlove
+> devices do not require Hand and Body Tracking to be enabled on the HMD device.
+> Enabling this feature is only necessary if you wish to use hand-tracking as a
+> fallback option when no glove is connected to your PC.
+
+### SteamVR App
+
+After enabling the [OpenXRViveTracker plugin](#openxrvivetracker-plugin) and [enabling `Emulate VIVE Wrist Tracker as VIVE Tracker` for VIVE HMDs relying on the VIVE Business Streaming](#vive-business-streaming-app), you need to perform one final setup in the SteamVR app for the SenseGlove Unreal Engine Plugin to be able to retrieve the correct wrist-tracking offsets. Once you have paired your VIVE Trackers or VIVE Wrist Trackers, navigate to `SteamVR Settings > Controllers > MANAGE TRACKERS` and make sure your left tracker is set to `LEFT FOOT` and the right tracker is set to `RIGHT FOOT`:

Instead, we require the `XR_HTCX_vive_wrist_tracker_interaction` OpenXR extension to be able to use VIVE Wrist Trackers on Android, which is provided by the [`ViveOpenXR` plugin](#viveopenxr-plugin). So, you can safely ignore enabling this plugin for Android standalone deployments.
+
+### ViveOpenXR Plugin

 To enable the SenseGlove Unreal Engine Plugin to track the gloves position and rotation in the world, you need to specify a positional tracking hardware, referred to as Wrist Tracking Hardware within the plugin. By default, if the Wrist Tracking Hardware is not explicitly set, the plugin will attempt to automatically detect it by identifying your Head-mounted display (HMD) hardware. However, this auto-detection feature may not be entirely reliable, as it is still experimental, and it may occasionally fail.
 
 For detailed information, please visit [the Wrist Tracking Hardware and HMD auto-detection configuration section](../../plugin-configuration/plugin-settings/tracking/wrist-tracking/).
+
+## Prerequisites
+
+Before you even consider setting up the Wrist Tracking Settings for the SenseGlove Unreal Engine Plugin, please make sure that you have already taken all the necessary steps in the [Enabling XR_EXT_hand_tracking OpenXR Extension on VR Headsets](../enabling-xr-ext-hand-tracking-vr-headsets/) section for [PCVR](../enabling-xr-ext-hand-tracking-vr-headsets/pcvr-mode/) or [Standalone](../enabling-xr-ext-hand-tracking-vr-headsets/standalone-mode/) modes. Otherwise, there's no guarantee that the plugin can access the location data from the wrist-tracking hardware of your choice. So, as the first troubleshooting measure, we always recommend double-checking the relevant prerequisite guides above.

+
+### Setting a Lower Refresh Rate
+
+The `ViveOpenXR` plugin provides various Blueprint functions to query the supported refresh rates and adjust the current refresh rate according to your needs:
+
+![HTC VIVE Specific Optimizations in Standalone Mode - ViveOpenXR plugin refresh rate Blueprint functions](htc-vive-specific-optimizations-standalone-mode-viveopenxr-refresh-rate-blueprint-functions.png "HTC VIVE Specific Optimizations in Standalone Mode - ViveOpenXR plugin refresh rate Blueprint functions")
+
+But, before you'd be able to make these adjustments you have to enable the relevant settings by navigating to `Edit > Project Settings > Plugins > Vive OpenXR` and ensure the `Enable Display Refresh Rate` option is checked. This option enables the OpenXR extension `XR_FB_display_refresh_rate` support which allows your application to dynamically adjust the display refresh rate in order to improve the overall user experience. Please note that You need to restart the engine to apply new settings after changing this setting.

+
+In order to query all the available display refresh rates use the Blueprint function `Enumerate Display Refresh Rates`:
+
+![HTC VIVE Specific Optimizations in Standalone Mode - Enumerating the available display refresh rates](htc-vive-specific-optimizations-standalone-mode-enumerate-display-refresh-rates.png "HTC VIVE Specific Optimizations in Standalone Mode - Enumerating the available display refresh rates")
+
+At the moment with most devices it returns `75.0` and `90.0` hz values.
+
+To change the current display refresh rate use the Blueprint function `Request Display Refresh Rate`:
+
+![HTC VIVE Specific Optimizations in Standalone Mode - Changing the current display refresh rate](htc-vive-specific-optimizations-standalone-mode-request-display-refresh-rate.png "HTC VIVE Specific Optimizations in Standalone Mode - Changing the current display refresh rate")
+
+To obtain the current display refresh rate use the Blueprint function `Get Display Refresh Rate`:
+
+![HTC VIVE Specific Optimizations in Standalone Mode - Obtaining the current display refresh rate](htc-vive-specific-optimizations-standalone-mode-get-display-refresh-rate.png "HTC VIVE Specific Optimizations in Standalone Mode - Obtaining the current display refresh rate")
+
+If you're looking to squeeze more performance out of your HTC VIVE HMD in standalone mode, consider lowering the target refresh rate from `90hz` to `75hz`. This can help reduce GPU workload and improve overall stability while still maintaining a somewhat smooth experience.
+
+### HTC VIVE Optimal Rendering Settings
+

 ## Game User Settings and Engine Scalability Settings
 
 Unreal Engine offers predefined graphics quality profiles known as Engine Scalability Settings, which can be easily adjusted to optimize performance. These settings can be modified directly within the Unreal Editor through the Settings menu on the toolbar or dynamically at runtime using code. Importantly, these settings are universal, meaning changes made in the Unreal Editor will apply to the game when run in PIE (Play In Editor) mode, and settings adjusted via code will also affect the editor itself.

+## OpenXRPositionalTrackingProvider
+
+Specifies the type of OpenXR provider to use in order to extract the positional tracking data from the underlying XR system. If set to None, the plugin attempts to set this automatically by considering a combination of approaches including, the current value of `TrackingHardware` specified below, the platform it's targeted at, the available OpenXR plugins, along with HMD auto-detection mechanism to specify a compatible OpenXR tracking provider. Please note that the OpenXR provider depends on the combination of plugins, platform, and the settings you use. For example, it is possible to use a Vive Focus 3 Wrist Tracker on Microsoft Windows along with the Epic `OpenXRViveTracker` plugin and check the option `Emulate VIVE Wrist Tracker as VIVE Tracker` inside the VIVE Business Streaming application's Input settings. In that case, the correct OpenXR positional tracking provider to use would be `OpenXRViveTracker`. However, using the official ViveOpenXR plugin on Android, the correct OpenXR provider would be `OpenXRViveWristTracker`.
+
+> [!CAUTION]
+> HMD auto-detection is currently an experimental feature and may fail because
+> HMD vendors occasionally change the properties utilized by the plugin for HMD
+> detection. If you encounter issues, such as incorrect tracker offsets, it is
